As their second collaboration with pop star Britney Spears, Indian design team Falguni & Shane Peacock have once again contributed to the singer's music video wardrobe. Spears is spotted wearing a white feathered mini-dress with a billowing satin train in the desert for her new single, 'Work Bitch'.

This follows the time she wore a similar-looking red dress from the Peacock label in her 2011 video, 'Hold It Against Me'. See below.

"This was commissioned by Britney's styling team," Falguni explains of their latest collaboration. "They had a very specific brief because they go into the minutest details when planning a video on this scale."

The Peacocks were asked to create a white and black garment dress with an element of fluidity, which they chose to do via the satin train.

"They wanted the train to be at least 40-50 feet long, and they'd even asked us to send extra fabric in case they needed to make it even longer," Falguni adds.

The whole process from briefing to sketching and then creating the garment took the designer duo a little over a week, a rather short turnaround time.

"We've worked with them many times in the past and have developed a good rapport, so we understood exactly what they were looking for," the designer says, explaining that there are more big ticket collaborations in the future.

Although they won't reveal names just yet — confidentiality clauses forbid it — the designers have already worked with Lady Gaga, Fergie and of course, Spears.
